The sensor is in the workshop and I need to work with this signal at home...
It's a signal from inductive sensor which measures RPM of motor shaft. Each peak is synchronized with TDC of piston. I also need to control the frequence of emulated signal to simulate the speed changes.
I would record the signal to file after acquiring with a DAQ card.
Then you could read this signal from the file and build it into a waveform. To change the frequency, just modify the value for dT that you bundle into the waveform.
